(Operation of the embodiment)
The engine is started, the machine is driven by the traveling device 2, the chopping device is cut by the reaping device 4, and the chopped culm is supplied to the threshing device 3 for threshing.
The threshed grain is temporarily stored in the Glen tank 5 and when a certain amount is stored, the discharge spiral discharge horizontal spiral 10 in the Glen tank 5 is operated, and the grain in the Glen tank 5 is discharged by the discharge horizontal spiral 10. It is conveyed to the discharge device 12.
The discharging device 12 connects the lower part of the fixed whipping cylinder 13 to the connection metal 11 provided in the glen tank 5, and provides the whipping spiral 17 in the fixed whipping cylinder 13 of the discharging device 12. The upper part is connected to an upper fixed connection metal 18 provided on the upper part of the fixed milling cylinder 13. An upper movable connection metal 19 is rotatably attached to the upper fixed connection metal 18, and the upper fixed connection metal 18 and the upper movable connection metal 19 are attached. Inside, the spiral shaft 21 of the takeover spiral 20 is mounted, and the movable discharge cylinder 14 is configured to be rotatable up and down with the axis of the spiral shaft 21 as a fulcrum, so that the grain conveyed by the discharge horizontal spiral 10 Enters the fixed cereal cylinder 13 of the discharge device 12 via the connection metal 11 and is cerealed on the upper fixed connection metal 18 by the cerealing helix 17 of the fixed cereal cylinder 13, and the cerealed grain is fixed on the upper side. Move upward from connecting metal 18 Is conveyed by the take-over spiral 20 to the metal 19 is conveyed discharged by the discharge spiral 23 enters the takeover helix 20 in the movable discharge cylinder 14.

Since the discharge device 12 is configured such that a movable discharge cylinder 14 shorter than the total length of the fixed cereal cylinder 13 is attached to the upper part of the fixed cereal cylinder 13 so as to be pivotable in the horizontal direction, The movable discharge cylinder 14 in the horizontal position is placed above the tank 27 of the grain transport vehicle 26, and the grain is discharged to the tank 27.
The movable discharge cylinder 14 rotates with the upper part of the fixed cereal cylinder 13 as a rotation fulcrum, so that the grain can be discharged in the state where the tank 27 of the grain transport vehicle 26 is close to the machine body including the Glen tank 5. This facilitates the discharge operation.
That is, when the lower part of the conventional milling cylinder is turned around the fulcrum, the tank 27 cannot be brought close to the part where the milling cylinder is slanted. Since the tank 27 is positioned below, the grain can be discharged by bringing the tank 27 close to the vicinity of the Glen tank 5.
Therefore, in this application, a grain discharge operation can be performed under a wide range of field conditions and work conditions.

In addition, the position of the discharge port of the discharge device 12 is usually aligned with a light truck that is stopped on a narrow path in the field, but in a configuration in which the conventional cereal cylinder is tilted with the lower part as a fulcrum and discharged, Since it becomes discharge | emission and it cannot discharge | emit in a horizontal state like this application, it is not easy to align the position of the discharge port of the discharge device 12.
In this regard, in the present application, after the movable discharge cylinder 14 is rotated to the horizontal state, the combine body may be brought close to the tank 27, and discharge work including alignment is facilitated.
In addition, in the conventional tilting-type discharging milling cylinder of the lower fulcrum, there is a possibility that the discharging milling cylinder may tilt during the movement of the machine, but in the present application, since the movable discharging cylinder 14 faces downward, There is no fear.
Further, since the movable discharge cylinder 14 of the discharge device 12 can be discharged even in the vertical state (vertical state), the grain filling bag 15 can be disposed under the movable discharge cylinder 14 to perform the discharge operation. Makes the discharge work easier.

In addition, when the height of the tank 27 of the transport vehicle 26 is low, the movable discharge cylinder 14 is rotated upward after approaching the airframe, but the movable discharge cylinder 14 is rotated upward depending on working conditions. Thus, the machine body can be brought close to and the work form is arbitrary, and in this respect as well, various work forms can be selected and workability can be improved.
Since the discharge spiral 23 is mounted in the movable discharge cylinder 14, even when the movable discharge cylinder 14 is discharged in an inclined state, the grain is smoothly conveyed by the discharge spiral 23.
Since the discharge port 24 of the movable discharge cylinder 14 is provided with a shooter 25 that can be extended and contracted, it is easy to align the tip discharge position of the shooter 25 with respect to the tank 27 and the grain filling bag 15 of the grain transporting vehicle 26, Ease discharge work.
Since the operation handle 30 is provided on the rear outer peripheral surface of the movable discharge cylinder 14, the position of the discharge port 24 of the movable discharge cylinder 14 can be adjusted by the operation handle 30 and the operability can be improved.

Since the bag receiving base 32 on which the grain filling bag 15 is placed is provided below the movable discharge cylinder 14 in the vertical position, the grain filling bag 15 is placed on the bag receiving base 32. At the time of “bag removal” discharge, the grain is discharged and filled in a state where the posture of the grain filling bag 15 is stabilized, and the operability is improved.
The upper fixed connection metal 18 and the upper movable connection metal 19 that connect the upper part of the fixed cereal cylinder 13 and the movable discharge cylinder 14 are arranged at a position higher than the upper surface of the Glen tank 5, so that the movable discharge can be performed for maintenance or the like. When the glen tank 5 is opened while the cylinder 14 remains in a horizontal state, mutual interference such as contact between the glen tank 5 and the movable discharge cylinder 14 is prevented.
In another embodiment of the discharge device 12 of FIG. 4, the movable discharge tube 14 attached to the fixed whipping tube 13 is configured to be substantially the same as the entire length of the fixed whipping tube 13, so that the lower portion is inclined as a fulcrum. The grain filling operation to the grain filling bag 15 can be performed at a place closer to the milling cylinder to be performed, and workability can be improved.

Since the movable discharge tube 14 of the discharge device 12 is provided with a support device 35 that supports the movable discharge tube 14 at an arbitrary position from a substantially vertical state to a substantially horizontal state, the tip of the support rod 36 of the support device 35 is attached to the movable discharge tube 14. When selectively engaged with the engaging groove 37, the movable discharge cylinder 14 is supported by the support device 35, and the discharge operation can be easily performed.
Since the rotation of the movable discharge cylinder 14 of the discharge device 12 is performed by the rotation drive device 40, the output gear 45 is rotated in the forward and reverse directions by the motor 44, the rotation shaft 41 is rotated, and the movable discharge cylinder 14 is rotated. Rotate.
8 to 10, the output gear 45 is attached to one end of the output operation shaft 50, the other end of the output operation shaft 50 faces the control unit 6, and the output operation shaft 50 Since the handle 51 is attached to the other end, the output operation shaft 50 is rotated forward and backward by the handle 51, the output gear 45 is rotated, and the movable discharge cylinder 14 is rotated.
Note that each of the above-described embodiments is illustrated or described separately or mixed for easy understanding, but these can be combined in various ways, and the expression, configuration, action, etc. It is not limited, and there are of course cases where a synergistic effect is obtained.
